The air cushion headbox control system mainly controls the pressure and liquid level inside the headbox. By adjusting the rotational speed of the flushing pump and the Roots blower, the sizing amount of the flushing pump and the amount of air blown by the Roots blower will be changed.
The dilution method can be roughly divided into mixed box type (mostly used for rotary wire paper machines and low-speed narrow-width Fourdrinier paper machines) and punching tank type.
The headbox is a key component of a modern paper machine and the key hub connecting the two parts "conveying" and "forming".
The Air-cushioned Headbox is composed of a square cone tube device, a homogenization roller device, an upper lip plate adjustment device, a box, a control system, a spray device, an air circuit system and other parts. The headbox is specially designed according to the working condition parameters provided by the user to ensure the working performance.
